Re: Help with impeller replacement
This copied verbatum from the Seloc Manual (except for my commentary) <br /><br />1 - Remove the three bolts securing the rear cover to the upper gear housing (the water pump access cover).<br /><br />2 - Lift the cover free of the upper gear housing. (duh) <br /><br />3 - Remove the three bolts securing the water pump housing.<br /><br />4 - Rotate the housing and pull it free. The seal, liner, and water pump impeller will all remain with the water pump housing. If the impeller failed to stay with the housing, pull it free from the pump shaft. If the impeller remained in the pump housing, pull it free with a pair of pliers. Do NOT remove the pump liner unless it is scored or worn. To remove the liner, pull it free with a pair of pliers.<br /><br /> SPECIAL WORDS <br />A new liner is included in a Cobra water pump repair kit, as shown in the accompanying illustration. (which you have to buy the book to see!) <br /><br />5 - Pry the pump plate free of the water pump adapter, using a gasket removal tool. Remove and discard the gasket from under the plate.<br /><br />There is another 2 pages of cleaning procedures and picture, but any self-respecting DIYer shouldn't need to be told that. I have recently done this, and it assumes you have the kit, not just the impeller. reassemble in reverse order. The tricky part is getting the funny shaped seal in place when reinstalling. Torque the housing bolts to 108 - 132 in/lbs, and the cover bolts the same.
Dang, that was a lot of typing! Oh well, maybe someone else can use it!
